My Python Program won't stop printing...

Ok so me and my friend are doing a weekend challenge... Whoever makes the best game wins.
Im trying to make a game like farmville but its called mineville and its just a little different. My problem is that theres this part in the code that keeps repeating, and i can't get it to stop. What should i do? Please keep it simple as i am just a beginner. Here's the code.

It might look familiar to some of you because i got it from my 'Python for the Absolute Beginner' book. (Don't worry, the challenge allowed the use of our programming books. Lol) Any help would be greatly appreciated! Thanks in advance.
